I don't agree with the Chakra reserves point, as Sasuke was compared to Madara by Kurama as well and that was a statement on their chakra. Uchiha Chakra is more sinister as they gain more power. Then we have Kakashi's statement from part one how Sasuke - like Naruto - had large chakra reserves. I highly doubt he stopped after that.
Given all this, Hashirama takes this probably High Difference because of Enton manipulation, I believe. His Mokuton Dragon doesn't seem to affect Susano'o as it was grabbing it and yet it wasn't losing its shape, but all other Ninjutsu including Amaterasu should be negated by sprouting more Mokuton and Hashirama has shown to create quite massive ones.
How Hashirama wins is through creating Mokuton-Bushins - he could create 5 and 6 more readily when he lost the first ones and stated that that's all he could maintain. Meaning, he should be able to create more than double the amount easily. Granted Sasuke would put on a better fight than Madara given that as his Mokuton would strike PS it would be covered with Enton, proving to be quite the hazard for Hashirama.
However, Hashirama can outlast Sasuke, as his Chakra reserves are quite massive - biggest in the manga bar the Juubi's Jins. The fact that he has the reserves to outlast Sasuke makes me want to hand this fight over to him. I believe it's only fair. Kurama however can be easily controlled with 3T, as Obito, Madara, and Sasuke showed. It's BS that Sasuke cannot.
That 14 your old kid was nothing but a copy of Madara at that time.
Sasuke was already able to control Manda with his 3 tomoe not to mention
he was even able to suppress Kyuubi chakra with his ''weak'' genjutsu [

So your statement is invalid.
edit: Lol at Obito being the greatest Genjutsu user... smh.
Don't bother with him - he's a new time of in-heat fruity Catherine here on NB - the more you try to drill, the more slutty it gets.
